How can content be loaded before redirecting to an external URL in PHP?

To load content before redirecting to an external URL in PHP, you can use output buffering to capture the content before sending any output to the browser. This way, you can perform any necessary operations or include content before redirecting the user to the external URL. 

<?php
// Start output buffering
ob_start();

// Your content goes here
echo "Hello, this is some content.";

// Store the content in a variable
$content = ob_get_clean();

// Perform any necessary operations

// Redirect to external URL
header("Location: https://www.externalurl.com");

// Make sure to exit after redirecting
exit;
?>
